Why are stickers so popular in Japan right now?

The sticker at the center of it

Most reporting traces the boom to one product. The Mainichi Shimbun reports that Bonbon Drop stickers were launched in March 2024 by Q-Lia, a stationery maker in Osaka's Chuo Ward. The idea came from designer Nao Yamazaki, then 28, who said she wanted to develop small decorative items with easy-to-use transparency and a three-dimensional feel. The team picked the name to evoke candy and gummies.

The construction is what makes them different. According to the Mainichi, each sticker is printed on both the base and the raised surface, with resin poured in between, so the two prints line up and the sticker throws a reflection when held up to the light. They come in plastic cases shaped to fit.

Sales were good from the start, but the Mainichi says popularity soared after a December 2024 collaboration with Sun-Star Stationery that put Sanrio and Disney characters on the stickers. The Yomiuri Shimbun adds the manga and anime franchise Chiikawa to that list. The scale is large: the Yomiuri reported more than 10 million sheets shipped within about a year and a half of release, and Nikkei Asia put the total at more than 15 million sheets sold by February 2026.

Trading at school, with its own exchange rates

The stickers are not only bought, they are swapped. The Mainichi reports that sticker exchanges have come back among elementary and junior high school students, and that several makers now sell sticker binders: clear, notebook-like holders with no printed designs, so the stickers stand out. Those binders have been selling out too.

Trades follow informal prices. A second-grader in Tokyo's Shinagawa Ward told the Yomiuri that trading at her school had intensified since the previous summer, and that popular and rare stickers command high rates, meaning you need several easier-to-find, thinner stickers to get one. Nikkei Asia put a number on it: a single Bonbon Drop sticker might be worth three regular stickers in a trade.

Nikkei Asia describes the negotiation itself as a big part of the appeal. Collectors learn to arrange exchanges that get them the stickers they want at the best value. The same report notes that this kind of trading echoes similar fads from the 1990s and early 2000s.

Why adults are buying them too

Nostalgia is the second engine. A collector known as Seal Daijin, who owns more than 10,000 stickers and has written a book on them, told the Mainichi that the Heisei girls trend, in which women in their 20s and 30s reminisce about things they loved as children, led to a surge in bulk buying. The Heisei era ran from 1989 to 2019.

Kwansei Gakuin University professor Koji Namba, who studies cultural sociology, told the Yomiuri that children are collectors by nature. Earlier generations collected stamps or milk bottle caps, and in the 1980s it was Bikkuri-Man stickers given away with snacks. He also pointed out that people who were in elementary school during the sticker boom of the late 1990s and early 2000s are now parents, and many enjoy exchanging stickers with their own children.

Q-Lia sees the same thing from the inside. Kazumasa Okamura of the company's development department told the Mainichi that sticker booms have come and gone before, but this is the first craze he has seen that captivates both children and adults. Nikkei Asia notes that collectors also show off planners decorated with the stickers on social media.

Sold out, resold and copied

Demand has outrun supply. Pan Pacific International Holdings, which runs the Don Quijote chain, told the Yomiuri that sticker sales had skyrocketed since October and now rival overall stationery sales, selling out the same day they arrive at stores across Tokyo. An official compared them to antibacterial goods during the pandemic.

Nikkei Asia reported in February 2026 that the home goods chain Loft had suspended sales at all of its locations because of the burden on stores and the number of customers who appeared to be buying for resale. The retailer Shimamura's website crashed when it opened presales of 20 sticker sets, and it stopped the presales. On the resale app Mercari, one listing offered 27 sheets for 330,000 yen, more than 2,100 US dollars.

Counterfeits followed. Sun-Star said on its website that it will take legal action against anyone selling fakes, and that fakes often leave the Sun-Star name and the character owner's information off the packaging. The Mainichi reports that similar and counterfeit products have reached store shelves and that some customers bought them without realising.

Common mistakes for new collectors

Paying resale prices without checking the packaging. A sheet listed far above its shop price is the kind of listing Sun-Star's warning is aimed at. If the maker's name and the character owner's details are missing from the pack, that matches what Sun-Star says many fakes look like.

Assuming every sticker trades one for one. Children trading at school already work with rates, as the Yomiuri and Nikkei Asia reports show. Agree on the rate before anything changes hands, especially when a puffy 3D sticker is on one side and flat ones are on the other.

Forgetting what a sheet costs. The Mainichi puts Bonbon Drop sheets at around 500 yen, and Nikkei Asia quotes 550 yen for a sheet of around 40 stickers, which it calls relatively expensive for a child's budget. The Mainichi notes that a sheet is often seen as a reward for a child's achievement, such as a good test score.

Thinking the hunt is the only way in. Nikkei Asia reports that as shortages dragged on, some children started trading binders of actual snacks, and an Osaka company, Konishi, began trending online for a clear-drying glue people use to make their own 3D stickers. SealPop takes another route: it turns your own photos into domed, glossy digital stickers on your phone, and two friends sitting together can trade one each by scanning a QR code.
